Greenland is the 12th largest country in the world, yet its entire population would just barely be able to fill Michigan Stadium to half of its capacity. Virtually all pictures taken on the enormous island encapsulate this sparsely populated, remote nature, such as this one taken by Mads & Trine on Flickr. Greenland is a place with towns so small they have almost no signs, as residents already know where everything is. This photo was taken in Sisimiut, a town with a quaint population of just over 5,000 where the local school turns into a hostel for the summer. Located just north of the Arctic Circle, it’s an ideal place to catch the Northern Lights.

The idea of “adventure travel” is hot and those who sell travel know it. Travelers who lead an active lifestyle as a big part of their everyday life want to continue that focus when traveling. Local adventurers who might camp, hike, hunt, ski or bike around where they live, want the thrill of doing that in an amazing place somewhere else on the planet. Even travelers once satisfied with a pre-packaged land tour or the standard fare on a Caribbean cruise want more. Only one problem: not everyone who likes the idea of adventure travel is equipped to handle it. But they still want it.

Enter land tour operator Abercrombie and Kent, known for safe and luxurious safari-like travel packages with a hefty price tag.

Offering more than a lazy man’s adventure, Abercrombie and Kent (A&K) recently announced a 2014 lineup of cruises to the Arctic. These luxury versions of the frigid expedition sailings for hearty explorers, normally associated with that part of the world, might very well be just what the pseudo-adventure traveler has in mind too.

On their July 29, 2014, sailing – Arctic Cruise Norway: Polar Bears & Midnight Sun – A&K guides take their guests to see polar bears, walrus and reindeer from the northern shores of Norway to the Svalbard Archipelago and Spitsbergen (AKA the last stop before the North pole), setting foot on the coastal city of Tromsø and the polar bear stomping grounds of Nordaustlandet. The 12-day adventure starts at $8,995.Another choice – A&K’s Arctic Cruise Adventure: Norway, Greenland & Iceland (Aug 7-21, 2014) – boasts stunning wildlife, geological features and history on an intense 15-day Arctic voyage from Norway and Spitsbergen to the region’s most remote and magnificent islands.

Visiting polar bears on the Svalbard archipelago, Kejser Franz Joseph Fjords and Scoresby Sound in Greenland along with Iceland’s extinct Snaefellsjokull volcano among other stops is not a cheap swing around the Caribbean. This one will run you $11,995.

Think that sounds like a lot to pay? Not everyone does: A&K’s 2013 Arctic offerings sold out 10 months in advance. This video gives us an idea of why they might be so popular:

Considering a trip to see the Northern Lights? This year may very well be the best time to go. 2013 is the height of the 11-year solar cycle. September and October offer peak activity. They can be seen in Alaska, Norway, Finland and Canada on a clear night. Better yet, try viewing on a ship at sea.

Common tips for viewing the Northern Lights say to go North, inside the Arctic circle, bring along a good guide and get away from light produced by cities and towns. That’s exactly what Compagnie du Ponant, a little French-flagged cruise line is doing this autumn for one of the best aurora borealis viewing opportunities possible.

Specializing in expedition sailings to the poles, Compagnie du Ponant sails small ships that feature custom technology designed to preserve fragile marine ecosystems.The 15-day sailing begins in Kangerlussuaq, Greenland, on September 5, 2013 and ends in Quebec, Canada, whose old town is listed as a UNESCO world heritage site. Bringing along naturalists and experienced guides, passengers will get prepared for what they are about to see with background information and lectures about the origins, myths and mysticism on the way.A 10-year veteran of the Arctic, Compagnie du Ponant knows the best places to see the northern lights. Their luxury 264-passenger yacht Le Boreal will sail to the heart of the northernmost territory in Canada where passengers will view the polar lights from the bridge of the ship.

As if viewing the Northern Lights in near-absolute darkness was not enough, the voyage will visit a number of other trip-of-a-lifetime quality places like the village of Sisimiut in Greenland as well as the Inuit land of Nunavut, also a prime viewing location. There will be whale watching in the Baffin Sea and Saint Lawrence, white bears to see on Akpatok Island and a stop in Perce, known for its rock and Northern Gannets. To see all that, the state-of-the-art Le Boreal is complemented with a fleet of expedition Zodiac boats outfitted with satellite tracking.

On board, passengers will find five-star French service, including a choice of 132 staterooms or suites with sea views and private balconies, restaurants offering dining from casual to fine, a bar and lounge, and 24-hour in-room dining. There is also an outdoor pool with bar, panoramic terrace adjoining the indoor bar and lounge, library with Internet stations, medical center, Wi-Fi, in-room and on-board flat screen satellite TV with complimentary on-demand movies.

The all-inclusive experience is priced from $8,922 per person, based on double occupancy, flights included.

I’m in a northern state of mind. Perhaps it’s the hail tickity-tacking off my window, or maybe it’s because Gadling is sending me to Estonia this February. That’s right, I’ll be freezing my butt off for your edification and entertainment.

Reading about the great Estonian castles such as Narva and Paide, I wondered which is the northernmost castle in the world. That great provider of facile and not always accurate information, the Internet, came up with several answers.

Called Olavinlinna in Finnish, construction started in 1475. At the time, the sparsely populated Savo region was in the hands of the Swedish crown but the Russians also wanted it. In fact, the Russians wanted it so badly that they attacked it several times, even before the castle was finished. The Russians finally took it in 1714 and kept it until the region became part of Finland when that nation became independent in 1917.

A castle this old always has its share of legends. The most persistent is the tale that a beautiful maiden was walled up in the castle as a punishment for treason. She must have been innocent because a rowan tree grew near the spot, with flowers as white as her virtue and berries as red as her blood. A nearby spring has a water sprite, and the castle was once saved by a giant black ram that made so much noise the invaders fled.

There’s a museum of Orthodox religious items on site and you can even hire out the castle in case you want to get married in the far north. The town of Savonlinna is a four-hour train ride from Helsinki and hosts an annual opera festival.

%Gallery-176848%If you aren’t a traditionalist and any old fort will do, the prize for northernmost castle goes to Vardøhus Fortress at 70° 22′ 20″N on a Norwegian island in the Barents Sea. There was a castle there as early as 1306 to control the fur and fish trade but nothing remains above ground today, so while it once may have been the northernmost castle in the world, it’s no longer standing and doesn’t count in my book.

Instead there’s a well-preserved star fort from 1738 that offers tours. Star forts came into prominence in the late 15th century as an adaptation to early cannons, which could knock down a castle wall before you could say, “We’re facing superior technology, run!” These forts had earthen embankments faced with stone and were laid out in the shape of a star to deflect cannonballs and provide crossfire.

Vardøhus Fortress proved vital to Norway’s interests yet never saw action until World War II. It’s still operating today and the five-man garrison has the duty of firing a cannon on national holidays and also when the full disk of the sun first appears over the horizon on January 21. This event is a holiday in northern Norway. You can find out more about Vardøhus along with plenty of photos over on The Lost Fort blog.

While no stretch of the imagination could make Thule Air Base in Greenland a castle, you have to tip your hats to the men and women of the United States Air Force and their NATO allies for living at 76° 31′ 52″ N. That’s 750 miles north of the Arctic Circle. It’s said to be the northernmost military base in the world. I suspect the Russians would disagree if they were willing to divulge that sort of information.

Greenland’s official tourism website recently unveiled a new ad campaign that may have some travelers rethinking their next destination. Boasting a new tagline – “Rough. Real. Remote.” –these videos give us a glimpse of some of the amazing adventure travel opportunities that exist in the country, including sea kayaking along pristine shores or mountain biking past massive glaciers, which you’ll find in the video below.

I have to admit, Greenland wasn’t all that high on my list of places to visit, but after watching these clips, I’m definitely intrigued. Judging from this video, the country looks to be an outdoor enthusiast and active travelers dream.
